Description

Technical Field

[0001] The invention relates to the technical field of sorting devices, and in particular to a cutting and sorting device for pre-prepared fish fillets without pulp and a control system thereof. Background Art

[0002] "Pre-prepared fish fillets without paste" refers to a type of pre-processed fish fillets, which are usually suitable for quick cooking or frozen storage. The key feature of this type of fish fillets is that they are "without paste", which means that they do not need to be soaked, strained or marinated in water or other liquids in advance during the production process. This processing method allows the fish fillets to maintain their original taste and freshness, while facilitating rapid processing and use. In the fish fillet processing industry, fish fillets of different specifications need to be sorted, weighed and packaged. If these tasks are completed manually, not only will a large amount of manpower be required, but the product cost will also be significantly increased.

[0003] In this regard, an automatic weighing and sorting device is currently used to solve this problem. The device can classify and store fish fillets according to their weight, and use the relevant data screening principle to achieve product grading, so that fish fillets of different weights are automatically sorted into designated areas, achieving a continuous and efficient sorting effect. For example, a Chinese patent for an automatic weighing and sorting machine for tilapia (publication number CN212093313U) is proposed in the prior art to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: "It includes a frame, a driving device, a discharge port and a controller, and the driving device, the discharge port and the controller are all installed on the frame; the frame is provided with a chain, a plurality of weight sensors and a plurality of tray supports, and a plurality of tray supports are provided with trays, and the frame is also provided with a swinging mechanism. This technical solution realizes fully automatic weighing and sorting of tilapia, completely replacing the heavy work of weighing and sorting tilapia manually, reducing labor costs, and also improving processing efficiency, so that processing costs are greatly reduced."

[0004] However, there are still obvious shortcomings when using the above solution for slicing: due to the different cross-sectional areas of different parts of the fish, the sizes of the slices are different. For example, larger fish fillets are usually cut from the parts close to the fish body, while the fillets at the tail are smaller. When slicing, fish fillets of similar sizes are kept together. If they are directly used for packaging after slicing, some packages will mainly contain large pieces of fish fillets, while other packages will only contain small pieces of fish fillets. This uneven distribution not only affects the appearance and quality of the fish fillets, but is also not conducive to the consumer's experience. Summary of the invention

[0005] The object of the present invention is to provide a device for cutting and sorting pre-prepared fish fillets without pulp and a control system thereof, so as to solve the problem of uneven size distribution in the prior art when slicing and sorting.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A pre-prepared dish paste-free fish fillet cutting and sorting device comprises a conveying component; the conveying component comprises a first belt conveyor, a second belt conveyor and a third belt conveyor, the second belt conveyor is provided with three, and the third belt conveyor is used for conveying dinner plates, and also comprises: a classification component, arranged at the output end of the first belt conveyor, and used for dividing the fish on the first belt conveyor into three types of fish pieces, large, medium and small, according to the cut area; a slicing component, one of which is arranged at the output end of each second belt conveyor, and is respectively used for slicing fish pieces of different sizes; a transfer component, arranged between the first belt conveyor and the second belt conveyor, and is used for transferring the fish pieces to the corresponding second belt conveyor; three material taking racks are provided and correspond to the second belt conveyors one by one, and are respectively used for transferring and weighing the three types of fish fillets, large, medium and small; and a plate arrangement component, arranged on the material taking rack, and is respectively used for placing fish fillets of different sizes on the dinner plate.

[0008] By adopting the above technical scheme, by setting a classification component, the fish is first divided into three types of fish pieces, namely large, medium and small, according to the size of the cross-sectional area before slicing the fish, and then the slicing component is used to slice the fish pieces of different sizes and send them to the material taking rack, and the fish fillets of different sizes are regulated and plated according to the pre-set quantity and the total quality to be achieved through the plating component, and the large and medium-sized fish fillets are used to achieve the set total quality so that the size distribution of the fish fillets is basically uniform, and the small-sized fish fillets are used to make up for the insufficient quality so that the total quality of the fish fillets meets the standard, so that the fish fillets can be evenly loaded on the plate, thereby improving the customer's adaptation experience.

[0009] A further improvement of the technical solution of the present invention is that: the swing plate assembly includes a turning table rotatably connected to the bottom of the material picking rack, a swing plate motor is fixedly installed on the bottom of the inner wall of the turning table, the output end of the swing plate motor extends to the bottom of the turning table and is fixedly connected to a screw rod, the bottom of the turning table is fixedly connected to a fixed cylinder, the screw rod is rotatably connected to the fixed cylinder, the external thread of the screw rod is connected to a sliding sleeve, the outer wall of the turning table is hinged with a plurality of support rods, the bottom of the support rods is hinged with a strut, and the ends of the struts away from the support rods are hinged with the sliding sleeves; a clamping structure for clamping fish fillets is provided on the outside of the support rods.

[0010] By adopting the above technical scheme, by setting up supporting rods arranged in a ring shape, the cut fish fillets are received by the supporting rods in a horizontal state during slicing, and the total mass of the fish fillets is weighed at the same time, until the total mass of the fish fillets meets the requirements, the supporting rods are controlled to flip downward, and the fish fillets are fixed by the clamping structure during the flipping process. After flipping to the top of the dinner plate, the fish fillets are detached, so that the fish fillets can be arranged in a ring-shaped and equidistant manner on the dinner plate, thereby improving the beauty of the fish fillet arrangement.

[0011] A further improvement of the technical solution of the present invention is that the clamping structure includes a U-shaped plate fixedly connected to the side wall of the support rod, a pressure rod is rotatably connected between the inner sides of the U-shaped plate, the end of the pressure rod away from the U-shaped plate is fixedly connected to the pressure plate, the side wall of the pressure plate is fixedly connected to an iron block, the outer side wall of the turning table is fixedly connected to a plurality of fixing frames, the side of the fixing frame away from the turning table is fixedly connected to a giving way magnet, and the side wall of the giving way magnet is fixedly connected to a rubber pad; a limiting rod is fixedly connected between the inner walls of the U-shaped plates.

[0012] By adopting the above technical solution, before the supporting rod flips downward, the iron block is adsorbed on the giving way magnet under the action of magnetic force (there is a rubber pad between the two), and in this state the pressure rod is in contact with the limiting rod; during the flipping process, the iron block is separated from the giving way magnet, so that the pressure plate and the pressure rod are flipped downward under the action of the gravity of the iron block until they contact the fish fillet, at which time the fish fillet is affected by the pressure plate and the second supporting plate and will not fall off, thereby temporarily fixing the fish fillet; the flipping continues until the supporting rod exceeds the vertical state, causing the supporting rod to tilt (the second supporting plate is located obliquely below the supporting rod), at which time the second supporting plate is separated from the pressure plate, thereby releasing the fish fillet, and the fish fillet falls into the plate under the action of gravity to complete the plating.

[0013] A further improvement of the technical solution of the present invention is that a feeding motor is fixedly installed inside the feeding rack, the central axis of the turning table extends to the inside of the feeding rack and is connected to the output end of the feeding motor through a belt and pulley transmission, a weighing sensor is installed on the side of the support rod away from the support rod, and a second support plate is fixedly connected to the side of the weighing sensor away from the support rod.

[0014] By adopting the above technical solution, after the fish fillet is cut onto the second support plate, the weighing sensor on the corresponding support rod will weigh the quality information of the fish fillet. At the same time, by controlling the operation of the feeding motor, the turning table is driven to turn over, so that the adjacent supporting rods and the second support plate are rotated to the receiving position to receive the fish fillet. The feeding motor works once for each cutting, and the rotation angle is the angle between the two adjacent supporting rods.

[0015] The further improvement of the technical solution of the present invention is that: the slicing component includes a slicing table fixedly connected to one side of the second belt conveyor, the top of the slicing table is rotatably connected to the second gantry, one side of the second gantry is fixedly connected to the second cylinder, the second cutter is slidably connected between the inner sides of the second gantry, and the output end of the second cylinder is fixedly connected to the second cutter; the bottom of the slicing table is fixedly connected to the material-dispensing motor, and the output end of the material-dispensing motor is connected to the central axis of the second gantry through a synchronous wheel and a synchronous belt transmission; the top of the slicing table is concave toward the center and is away from the top of the second belt conveyor. The top is a plane structure; the top of the slicing table is fixedly connected to the mounting frame, one side of the mounting frame is fixedly installed with a second servo module, the movable end of the second servo module is fixedly connected to a movable plate, the top of the movable plate is slidably connected to two sliding rods, the top of the sliding rod is fixedly connected to a limiting block, the bottom of the sliding rod extends to the bottom of the movable plate and is fixedly connected to a push plate, the outside of the sliding rod and a spring is sleeved between the movable plate and the push plate, the bottom of the movable plate is fixedly connected to an electromagnet, and the top of the push plate is fixedly connected to an iron column used in conjunction with the electromagnet.

[0016] By adopting the above technical scheme, the fish block is conveyed to the front end of the slicing table through the second belt conveyor, and the iron column is attracted by the electromagnet by controlling the operation of the electromagnet, driving the push plate to slide upward, compressing the spring, and then controlling the operation of the second servo module to drive the movable plate to move and pass over the fish block; by controlling the electromagnet to cut off the power, the iron column is no longer adsorbed by the magnetic force, so that the push plate is pushed downward by the elastic force of the spring until the bottom of the push plate contacts the second belt conveyor; then, by controlling the operation of the second servo module, the movable plate and the push plate are driven to move, thereby pushing the fish block to the slicing position; after reaching the slicing position, the second cylinder is controlled to work to push the second cutter downward to complete the slicing of the fish block.

[0017] A further improvement of the technical solution of the present invention is that: the transfer component includes a turning frame, a transfer motor is fixedly connected to the inside of the turning frame, a bracket is rotatably connected to the top of the turning frame, the central axis of the bracket extends to the inside of the turning frame and is connected to the output end of the transfer motor through a belt and a pulley transmission, a plurality of rotating plates are connected to the bracket, a slide groove is provided on one side of the turning plate, two sliders are symmetrically slidably connected between the inner walls of the slide groove, the sliders are T-shaped, one side of the two sliders extend to the outside of the slide groove and are fixedly connected to the first support plate, the bottom of the first support plate is fixedly connected to a transmission plate, a connecting groove is provided on one side of the transmission plate, and transmission grooves are symmetrically provided on opposite sides of the transmission plate, two fourth cylinders are symmetrically fixedly connected to the bottom of the turning plate, the piston rod of the fourth cylinder extends to the inside of the connecting groove and is fixedly connected to the transmission rod, and the transmission rod is slidably connected to the transmission groove.

[0018] By adopting the above technical solution, after each cutting, the fish pieces are sent to the middle position on the top of the two first pallets, and the transfer motor is controlled to drive the bracket to flip until the first pallet moves to the top of the corresponding second belt conveyor, and then the fourth cylinder is controlled to work (the piston rod extends), pushing the transmission rod to move and squeeze the transmission groove, so that the two transmission plates move to the side away from each other, thereby separating the two first pallets, and the fish pieces between the two first pallets fall onto the second belt conveyor.

[0019] A further improvement of the technical solution of the present invention is that: the rotating plate is rotatably connected to the top of the bracket, the bottom of the bracket is rotatably connected to a plurality of gears, the top of the flip frame is fixedly connected to an inner ring gear, the inner ring gear is meshingly connected to the gears, the gears correspond to the rotating plate one by one, and the central axis of the rotating plate and the central axis of the gears are connected through a synchronous belt and a synchronous wheel transmission.

[0020] By adopting the above technical solution, a rotating plate that can automatically rotate as the bracket flips is set. During the flipping process of the bracket, the gear revolves around the central axis of the bracket. Since the gear is meshing with the inner ring gear, it will rotate itself during the process, and the rotating plate is driven to rotate through the synchronous belt and the synchronous wheel. The rotation direction is opposite to the rotation direction of the bracket and the speed is the same, so that the rotating plate maintains the same direction during the revolution, thereby ensuring the consistency of the direction during the conveying of the fish pieces.

[0021] A further improvement of the technical solution of the present invention is that: the classification component includes a first gantry, the first gantry is fixedly connected to the top of the first belt conveyor, the discharge end of the first belt conveyor is fixedly connected to a slitting table, and the slitting table is in contact with the conveyor belt on the first belt conveyor; the top of the first gantry is fixedly connected to a first servo module, the movable end of the first servo module is fixedly connected to a first cylinder, and the piston rod of the first cylinder is fixedly connected to a first cutter; a groove is provided at the top of the slitting table, an offset plate is rotatably connected inside the groove, a strip groove is provided on one side of the offset plate, a third cylinder is fixedly connected to the bottom of the slitting table, the piston rod of the third cylinder is fixedly connected to a push rod, the push rod is slidably connected to the strip groove, and a corner of the offset plate has a notch.

[0022] By adopting the above technical scheme, the fish is conveyed to the offset plate position by the first belt conveyor until the fish completely leaves the conveyor belt of the first belt conveyor, and then the third cylinder is controlled to extend to push the push rod upward, so that the offset plate is flipped up to a slightly inclined state, and the fish slides along the inclined surface to the intersection of the offset plate and the cutting table. A gap is generated at this position when the offset plate is flipped up, and the fish is blocked when it slides to this position; the third cylinder is controlled to be retracted to reset the offset plate (to a horizontal state), and the first servo module is controlled to work to drive the first cutter to move, so as to align with different parts of the fish. Two groups of sensors are arranged at the active end of the first servo module for measuring the size of the fish, one of which is used to measure the width of the fish from a bird's-eye view, and the other is used to measure the height of the fish. The above two groups of data are used to estimate the cross-sectional area data corresponding to the first cutter position, and compared with the set limit data, so as to realize the judgment of the cutting position.

[0023] The pre-prepared fish fillet cutting and sorting control system includes:

[0024] A data processing module is used to process the quality information collected by the weighing sensor;

[0025] The data comparison module is used to compare the quality data of the fish fillet with the set data. The data comparison process is carried out in order from large to small according to the fish fillet model;

[0026] A data judgment module, used to determine the number of medium-sized fish fillets according to the quality data of the large-sized fish fillets, and to determine the number of small-sized fish fillets according to the sum of the quality data of the medium-sized fish fillets and the large-sized fish fillets;

[0027] The instruction generation module generates instructions based on the data judgment results. When the quality does not meet the requirements, it controls the slicing component to slice. When the quality meets the requirements, it controls the plating component to perform the plating operation.

[0028] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0029] 1. The present invention provides a classification component to divide the fish into three types of fish pieces, namely large, medium and small, according to the size of the cross-sectional area before slicing the fish. The slicing component is then used to slice the fish pieces of different sizes and send them to a material taking rack. The fish pieces of different sizes are regulated and plated according to the pre-set quantity and the total required mass by the plate arrangement component. The large and medium-sized fish pieces are used to achieve the set total mass so that the size distribution of the fish pieces is basically uniform, and the small-sized fish pieces are used to make up for the insufficient mass so that the total mass of the fish pieces meets the standard, so that the fish pieces can be evenly loaded on the plate, thereby improving the customer's adaptation experience.

[0030] 2. The present invention provides support rods that are equidistantly arranged in a circular shape. When slicing, the cut fish fillets are received by the support rods in a horizontal state, and the total mass of the fish fillets is weighed at the same time. When the total mass of the fish fillets meets the requirements, the support rods are controlled to flip downward. During the flipping process, the fish fillets are fixed by a clamping structure, and the fish fillets are detached after flipping to the top of the dinner plate. The fish fillets can be arranged equidistantly in a circular shape on the dinner plate, thereby improving the aesthetic appearance of the fish fillet presentation.

[0031] 3. The present invention provides a transfer component. After each cutting, the fish pieces are sent to the middle position on the top of the two first pallets. By controlling the operation of the transfer motor, the bracket is driven to flip until the first pallet moves to the top of the corresponding second belt conveyor. Then the fourth cylinder is controlled to move the transmission rod and squeeze the transmission groove, so that the two transmission plates move to the side away from each other, thereby separating the two first pallets, and the fish pieces between the two first pallets fall onto the second belt conveyor.

[0032] 4. The present invention provides a rotating plate that can automatically rotate as the bracket flips. During the flipping process of the bracket, the gear revolves around the central axis of the bracket. Since the gear is meshed with the inner gear ring, it will rotate itself during the process, and the rotating plate is driven to rotate through the synchronous belt and the synchronous wheel. The rotation direction is opposite to the rotation direction of the bracket and the speed is the same, so that the rotating plate maintains the same direction during the revolution, thereby ensuring the consistency of the direction during the conveying of the fish pieces.

[0033] 5. The present invention provides a clamping structure that automatically releases during the process of plating. Before the support rod flips downward, the iron block is adsorbed on the giving way magnet under the action of magnetic force (there is a rubber pad between the two), and in this state, the pressure rod is in contact with the limit rod; during the flipping process, the iron block is separated from the giving way magnet, so that the pressure plate and the pressure rod flip downward under the action of the gravity of the iron block until they contact the fish fillet, at which time the fish fillet is affected by the pressure plate and the second support plate and will not fall off, thereby temporarily fixing the fish fillet; the flipping is continued until the support rod exceeds the vertical state, causing the support rod to tilt (the second support plate is located obliquely below the support rod), at which time the second support plate is separated from the pressure plate, thereby releasing the fish fillet, and the fish fillet falls into the plate under the action of gravity to complete the plating. At the same time, the fish fillet is arranged in a ring shape on the plate, so that there is no need to set up too many drives, saving the cost of the device and simplifying the device.

DETAILED DESCRIPTION

[0048] The present invention is further described in detail below in conjunction with embodiments:

[0049] Example 1

[0050] like Figure 1 , Figure 2 and Figure 7 As shown, the present invention provides a pre-prepared dish paste-free fish fillet cutting and sorting device, including a conveying component; the conveying component includes a first belt conveyor 1, a second belt conveyor 2 and a third belt conveyor 3, the second belt conveyor 2 is provided with three, and the third belt conveyor 3 is used to convey the dinner plate, and also includes: a classification component, arranged at the output end of the first belt conveyor 1, used to divide the fish on the first belt conveyor 1 into three types of fish pieces, large, medium and small, according to the cut area; a slicing component, each output end of the second belt conveyor 2 is provided with one, respectively used to slice fish pieces of different sizes; a transfer component, arranged between the first belt conveyor 1 and the second belt conveyor 2, used to transfer the fish pieces to the corresponding second belt conveyor 2; three material taking racks 41 are provided and correspond to the second belt conveyors 2 one by one, respectively used to transfer and weigh the three types of fish fillets, large, medium and small; a plate arrangement component, arranged on the material taking rack 41, respectively used to place fish fillets of different sizes on the dinner plate.

[0051] In this embodiment, by providing a classification component, the fish is first divided into large, medium and small sizes of fish fillets according to the size of the cross-sectional area before slicing, and then the slicing component is used to slice the fish fillets of different sizes and send them to the material rack 41. The fish fillets of different sizes are regulated and plated according to the pre-set quantity and the total required quality through the plating component. The large and medium-sized fish fillets are used to achieve the set total quality so that the size distribution of the fish fillets is basically uniform, and the small-sized fish fillets are used to make up for the insufficient quality so that the total quality of the fish fillets meets the standard, so that the fish fillets can be evenly loaded on the plate, thereby improving the customer's adaptation experience.

[0052] Specifically, the plating starts with large fish fillets to ensure that the number of large fish fillets is equal, and the total mass of the large fish fillets is compared with the total mass required for the large fish fillets set in advance. When the mass of the large fish fillets exceeds the set value of the mass of the large fish fillets, the amount of medium fish fillets placed is reduced according to the excess amount to ensure that the total mass of the medium and large fish fillets is close, and finally small fish fillets are added according to the total mass of the large and medium fish fillets until the mass required for the plating is reached.

[0053] Among them, the mass of the small fish fillet is less than twice the allowable error value of the total mass of the fish fillet, that is, when the total mass requirement of the fish fillet is 500±5g, the mass requirement of the small fish fillet is less than 10g, to ensure that the requirements can be met when the small fish fillet is used to compensate for the mass later.

[0054] like Fig. 9 , Fig.10 and Fig.11 As shown, preferably, the swing plate assembly includes a turning table 42 rotatably connected to the bottom of the material picking rack 41, a swing plate motor 43 is fixedly installed on the bottom of the inner wall of the turning table 42, the output end of the swing plate motor 43 extends to the bottom of the turning table 42 and is fixedly connected to a screw 44, a fixed cylinder 45 is fixedly connected to the bottom of the turning table 42, the screw 44 is rotatably connected to the fixed cylinder 45, the external thread of the screw 44 is connected to a sliding sleeve 46, a plurality of support rods 47 are hinged on the outer wall of the turning table 42, a support rod 48 is hinged on the bottom of the support rod 47, and the end of the support rod 48 away from the support rod 47 is hinged to the sliding sleeve 46; the outside of the support rod 47 is provided with a clamping structure for clamping the fish fillet.

[0055] When arranging fish fillets, if they are placed directly on the plate in batches, the fish fillets will be arranged unevenly, reducing the probability that customers will like them. Therefore, the plating process should not only consider the size and quality of the fish fillets, but also arrange them reasonably to improve the appearance of the fish fillets.

[0056] In this embodiment, supporting rods 47 are arranged equidistantly in a ring shape. When slicing, the cut fish fillets are received by the supporting rods 47 in a horizontal state. After the fish fillets are received, the supporting rods 47 are controlled to flip downward. During the flipping process, the fish fillets are fixed by a clamping structure. After flipping to the top of the dinner plate, the fish fillets are detached. The fish fillets can be arranged equidistantly in a ring shape on the dinner plate, thereby improving the aesthetic appearance of the fish fillet presentation.

[0057] Specifically, when plating, the plating motor 43 is controlled to work, driving the screw 44 to rotate, so that the sleeve 46 slides downward (the sleeve 46 is limited by the external support rods 48 and will not rotate), and the support rod 47 is driven to flip downward through the support rod 48, so that the fish fillet is flipped over the plate and released.

[0058] like Fig.10 and Fig.11 As shown, preferably, the clamping structure includes a U-shaped plate 53 fixedly connected to the side wall of the support rod 47, a pressure rod 51 is rotatably connected between the inner sides of the U-shaped plate 53, the end of the pressure rod 51 away from the U-shaped plate 53 is fixedly connected to a pressure plate 58, the side wall of the pressure plate 58 is fixedly connected to an iron block 52, the outer side wall of the turning table 42 is fixedly connected to a plurality of fixing frames 55, the side of the fixing frame 55 away from the turning table 42 is fixedly connected to a yielding magnet 56, and the side wall of the yielding magnet 56 is fixedly connected to a rubber pad; a limiting rod 54 is fixedly connected between the inner walls of the U-shaped plate 53.

[0059] In this embodiment, before the support rod 47 flips downward, the iron block 52 is adsorbed on the giving way magnet 56 under the action of magnetic force (there is a rubber pad between the two), and in this state, the pressure rod 51 is in contact with the limit rod 54; during the flipping process, the iron block 52 is separated from the giving way magnet 56, so that the pressure plate 58 and the pressure rod 51 are flipped downward under the gravity of the iron block 52 until they contact the fish fillet. At this time, the fish fillet is affected by the pressure plate 58 and the second support plate 50 and will not fall off, thereby temporarily fixing the fish fillet; continue to flip until the support rod 47 exceeds the vertical state, so that the support rod 47 is tilted (the second support plate 50 is located obliquely below the support rod 47), at this time, the second support plate 50 is separated from the pressure plate 58, thereby releasing the fish fillet, and the fish fillet falls into the plate under the action of gravity to complete the plating, and the fish fillet is arranged in a ring shape on the plate.

[0060] like Fig.10 and Fig.11 As shown, preferably, a feeding motor 57 is fixedly installed inside the feeding rack 41, the central axis of the turning table 42 extends to the inside of the feeding rack 41 and is connected to the output end of the feeding motor 57 through a belt and pulley transmission, a weighing sensor 49 is installed on the side of the support rod 47 away from the support rod 48, and a second support plate 50 is fixedly connected to the side of the weighing sensor 49 away from the support rod 47.

[0061] During the slicing process, the material taking motor 57 works once each time a cut is made, and the rotation angle is the size of the angle between two adjacent supporting rods, thereby switching the supporting rod 47 to receive the fish fillet (held by the second supporting plate 50). Specifically: after the fish fillet is cut onto the second supporting plate 50, the weighing sensor 49 on the corresponding supporting rod 47 weighs the quality information of the fish fillet. At the same time, by controlling the material taking motor 57 to work, the turning table 42 is driven to turn over, so that the adjacent supporting rods 47 and the second supporting plate 50 rotate to the receiving position to receive the fish fillet.

[0062] Before arranging the fish slices on the second support plate 50, the weight and mass of the fish slices on the second support plate 50 should be calculated, and the arranging of the fish slices on the plate can be started only after the weight reaches the requirement.

[0063] Preferably, the placement positions of fish fillets of different sizes can be controlled by controlling the material taking motor 57 when arranging the plate, so that the support rods 47 on different material taking racks 41 correspond to different positions of the plate (circumferentially), so that fish fillets of different sizes are interspersed in their respective gaps.

[0064] Example 2

[0065] like Figure 2 , Figure 5 and Figure 8 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the slicing component includes a slicing table 36 fixedly connected to one side of the second belt conveyor 2, the top of the slicing table 36 is rotatably connected to the second gantry 37, one side of the second gantry 37 is fixedly connected to the second cylinder 39, the inner side of the second gantry 37 is slidably connected to the second cutter 38, and the output end of the second cylinder 39 is fixedly connected to the second cutter 38; the bottom of the slicing table 36 is fixedly connected to the material-discharging motor 40, and the output end of the material-discharging motor 40 is connected to the central axis of the second gantry 37 through a synchronous wheel and a synchronous belt transmission; the top of the slicing table 36 is concave toward the center and away from the second belt The top of one side of the conveyor 2 is a flat structure; the top of the slicing table 36 is fixedly connected to a mounting frame 27, and a second servo module 28 is fixedly installed on one side of the mounting frame 27. The movable end of the second servo module 28 is fixedly connected to a movable plate 29, and the top of the movable plate 29 is slidably connected to two slide bars 30, and the top of the slide bar 30 is fixedly connected to a limiting block 32, and the bottom of the slide bar 30 extends to the bottom of the movable plate 29 and is fixedly connected to a push plate 31. A spring 33 is sleeved on the outside of the slide bar 30 and located between the movable plate 29 and the push plate 31, and the bottom of the movable plate 29 is fixedly connected to an electromagnet 35, and the top of the push plate 31 is fixedly connected to an iron column 34 used in conjunction with the electromagnet 35.

[0066] In this embodiment, the fish block is conveyed to the front end of the slicing table 36 by the second belt conveyor 2. By controlling the electromagnet 35 to work, the iron column 34 is attracted by the electromagnet 35, driving the push plate 31 to slide upward, compressing the spring 33, and then controlling the second servo module 28 to work, driving the movable plate 29 to move and pass over the fish block; by controlling the electromagnet 35 to cut off power, the iron column 34 is no longer attracted by the magnetic force, so that the push plate 31 is pushed downward by the elastic force of the spring 33 until the bottom of the push plate 31 contacts the second belt conveyor 2; then, by controlling the second servo module 28 to work, the movable plate 29 and the push plate 31 are driven to move, thereby pushing the fish block to the slicing position; after reaching the slicing position, the second cylinder 39 is controlled to work to push the second cutter 38 downward to complete the slicing of the fish block.

[0067] After each slicing, the material-discharging motor 40 is controlled to work, driving the second gantry 37 to tilt slightly, and the second cutter 38 tilts accordingly, so that the cut fish fillets are tilted toward the second support plate 50, and the fish fillets fall toward the second support plate 50, so that the fish fillets are "rested on" the second support plate 50.

[0068] Example 3

[0069] like Figure 4 , Figure 5 and Figure 6 As shown, on the basis of Example 2, the present invention provides a technical solution: preferably, the transfer component includes a turnover frame 13, the interior of the turnover frame 13 is fixedly connected to a transfer motor 24, the top of the turnover frame 13 is rotatably connected to a bracket 14, the central axis of the bracket 14 extends to the interior of the turnover frame 13 and is connected to the output end of the transfer motor 24 through a belt and a pulley transmission, a plurality of rotating plates 15 are connected to the bracket 14, a slide groove 16 is provided on one side of the rotating plate 15, and two sliders 1 are symmetrically slidably connected between the inner walls of the slide groove 16. 7. The slider 17 is T-shaped, one side of the two sliders 17 extends to the outside of the slide groove 16 and is fixedly connected to the first support plate 18, the bottom of the first support plate 18 is fixedly connected to the transmission plate 19, one side of the transmission plate 19 is provided with a connecting groove 20, and the two opposite sides of the transmission plate 19 are symmetrically provided with transmission grooves 21, and the bottom of the rotating plate 15 is symmetrically fixedly connected with two fourth cylinders 22, the piston rod of the fourth cylinder 22 extends to the inside of the connecting groove 20 and is fixedly connected with a transmission rod 23, and the transmission rod 23 is slidably connected to the transmission groove 21.

[0070] In this embodiment, after each cutting, the fish pieces are sent to the middle position on the top of the two first support plates 18, and the transfer motor 24 is controlled to work to drive the bracket 14 to flip until the first support plate 18 moves to the top of the corresponding second belt conveyor 2, and then the fourth cylinder 22 is controlled to work (the piston rod extends), pushing the transmission rod 23 to move and squeeze the transmission groove 21, so that the two transmission plates 19 move to the side away from each other, thereby separating the two first support plates 18, and the fish pieces located between the two first support plates 18 fall onto the second belt conveyor 2.

[0071] like Figure 4 and Figure 5 As shown, preferably, the rotating plate 15 is rotatably connected to the top of the bracket 14, the bottom of the bracket 14 is rotatably connected to a plurality of gears 26, the top of the flip frame 13 is fixedly connected to an inner ring gear 25, the inner ring gear 25 is meshingly connected to the gear 26, the gear 26 corresponds to the rotating plate 15 one by one, and the central axis of the rotating plate 15 and the central axis of the gear 26 are connected through a synchronous belt and a synchronous wheel transmission.

[0072] Since the fish pieces are sent to the second belt conveyor 2 by the transfer component and then sliced ​​after being transported, and the slicing is usually along the vertical direction of the fish bones, if the angle of the fish pieces is not uniform when they are sent from the transfer component to the second belt conveyor 2, the direction of the fish pieces needs to be adjusted to facilitate the subsequent slicing operation of the fish pieces;

[0073] In this embodiment, a rotating plate 15 is provided which can automatically rotate along with the flipping of the bracket 14. During the flipping process of the bracket 14, the gear 26 revolves around the central axis of the bracket 14. Since the gear 26 is meshed with the inner gear ring 25, it will rotate on its own during the process, and the rotating plate 15 is driven to rotate through the synchronous belt and the synchronous wheel. The rotation direction is opposite to the rotation direction of the bracket 14 and the speed is the same, so that the rotating plate 15 maintains the same direction during the revolution, thereby ensuring the consistency of the direction of the fish pieces during the conveying process.

[0074] Example 4

[0075] like Figure 1 and Figure 3As shown, on the basis of Example 3, the present invention provides a technical solution: preferably, the classification component includes a first gantry 4, the first gantry 4 is fixedly connected to the top of the first belt conveyor 1, the discharge end of the first belt conveyor 1 is fixedly connected to a slitting table 8, and the slitting table 8 is in contact with the conveyor belt on the first belt conveyor 1; the top of the first gantry 4 is fixedly connected to a first servo module 5, the movable end of the first servo module 5 is fixedly connected to a first cylinder 6, and the piston rod of the first cylinder 6 is fixedly connected to a first cutter 7; a groove is provided at the top of the slitting table 8, and an offset plate 9 is rotatably connected inside the groove, and a strip groove 11 is provided on one side of the offset plate 9, and a third cylinder 10 is fixedly connected to the bottom of the slitting table 8, and the piston rod of the third cylinder 10 is fixedly connected to a push rod 12, and the push rod 12 is slidably connected to the strip groove 11, and a corner of the offset plate 9 has a notch.

[0076] In this embodiment, the fish is conveyed to the position of the offset plate 9 by the first belt conveyor 1 until the fish completely leaves the conveyor belt of the first belt conveyor 1, and then the third cylinder 10 is controlled to extend to push the push rod 12 upward, so that the offset plate 9 is flipped up to a slightly inclined state, and the fish slides along the inclined surface to the intersection of the offset plate 9 and the cutting table 8. A gap is generated at this position when the offset plate 9 is flipped up, and the fish is blocked when it slides to this position; the third cylinder 10 is controlled to be retracted to reset the offset plate 9 (to a horizontal state), and the first servo module 5 is controlled to work and drive the first cutter 7 to move, so as to align with different parts of the fish. Two groups of sensors are arranged at the movable end of the first servo module 5 for measuring the size of the fish, one of which is used to measure the width of the fish from a bird's-eye view, and the other is used to measure the height of the fish. The above two groups of data are used to estimate the cross-sectional area data corresponding to the position of the first cutter 7, and compared with the set limit data, so as to realize the judgment of the cutting position.

[0077] It should be noted that during the slicing process, the first cutter 7 is not retracted after each cut, but the first servo module 5 is controlled to work, driving the first cutter 7 to move, thereby pushing the cut fish pieces to move until the fish pieces are pushed onto the first support plate 18.

[0078] The present invention also provides a pre-prepared fish fillet cutting and sorting control system, comprising:

[0079] A data processing module, used to process the mass information collected by the weighing sensor 49;

[0080] The data comparison module is used to compare the quality data of the fish fillet with the set data. The data comparison process is carried out in order from large to small according to the fish fillet model;

[0081] A data judgment module, used to determine the number of medium-sized fish fillets according to the quality data of the large-sized fish fillets, and to determine the number of small-sized fish fillets according to the sum of the quality data of the medium-sized fish fillets and the large-sized fish fillets;

[0082] The instruction generation module generates instructions based on the data judgment results. When the quality does not meet the requirements, it controls the slicing component to slice. When the quality meets the requirements, it controls the plating component to perform the plating operation.

[0083] The working principle of the pre-prepared dish paste-free fish fillet cutting and sorting device is described in detail below.

[0084] like Figure 1-Figure 12 As shown, the deboned fish is placed on the first belt conveyor 1, and the fish is conveyed to the offset plate 9 by the first belt conveyor 1, and the fish is cut into three types of fish pieces, namely large, medium and small, by the classification component. After the cutting is completed, the fish pieces are transferred to the corresponding second belt conveyor 2 by the transfer component, and are conveyed to the slicing position, and the fish pieces of different sizes are sliced ​​by the slicing component and sent to the material taking rack 41, and the fish pieces of different sizes are placed according to the pre-set quantity and the total quality to be achieved by the plate arrangement component. The number of large fish fillets is the same. Since relatively more parts of the fish body are divided into large fish fillets, and the proportion of large fish fillets is preliminarily confirmed based on the proportion of this part, a fixed number of large fish fillets are directly used when taking them. When the mass of this group of large fish fillets exceeds the set value of the mass of large fish fillets, the amount of medium fish fillets placed is reduced according to the excess amount to ensure that the total mass of medium and large fish fillets is close, and finally small fish fillets are added according to the total mass of large and medium fish fillets until the mass required for plating is reached, so that the fish fillets can be evenly placed on the plate. The placing process is directly controlled by controlling the material taking motor 57 to drive the turning table 42 to turn over, so that the adjacent support rods 47 and the second support plate 50 rotate to the receiving position to receive the fish fillets; when arranging the plate, the plate arranging motor 43 is controlled to work, which drives the screw 44 to rotate, so that the sliding sleeve 46 slides downward (the sliding sleeve 46 is limited by the external support rods 48 and will not rotate), and the support rod 47 is driven to turn downward by the support rod 48, so that the fish fillets are turned over to the top of the plate and released. For different types of fish fillet placement positions, the material taking motor 57 can be controlled to work when arranging the plate, so that the support rods 47 on different material taking racks 41 correspond to different positions on the circumference of the plate.

[0085] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
